Question

a person buys 2 watches for rs.1100 and he sells one at a profit of 5 percent and the other at x percent loss. on the whole if there is no profit no loss. find x​

Answer 1

Answer:

loss% = 5% or x% = 5%

Step-by-step explanation:

CP of 2 watches = ₹1100

Hence, CP of each watch = ₹550

(1) profit% on first watch = 5%

hence SP of first watch = ₹577.5

₹577.5 - ₹550 = ₹27.5

•if there is no profit or loss we need to subtract ₹27.5 from the CP of 2nd watch.

CP of each watch = ₹550.

₹550 × x%

₹550 × x/100 = ₹27.5

x/100 = 27.5/550

x/100 = 275/5500

x/100 = 1/20

x = 1/20 × 100

x = 100/20

x = 5

Hence, x% = 5%
